VALVE AND CONNECTION THEREFOR.

To all whom it may concern Be it known that I, ELLIOTT BOLLAND, asubject of the King of Great Britain and Ireland, &c., residing atCharters Towers, in the State of Queensland, Commonwealth of Australia,have invented certain new and useful Improvements in and Relating toValves and Connections 'lherefor; and I do hereby declare the followingto be a full, clear, and exact description of the invention such as willenable others skilled in the art to which it appertains to make and usethe same.

The invention relates to valves and taps and connections for theiroperation.

My construction is adapted for many situations including especiallythose in which it is desired to have a valve which will be guardedagainst being mischievously han dled.

My valve cannot rattle in its casing, and the construction is alsootherwise advantageous.

Glass, earthenware, metal, or other suitable material or combination ofmaterials may be used.

The valve is opened by screwing up a collar or union nut carried by atubular tail piece or the like, and is closed on its seat by fluidpressure when the collar is unscrewed. Screwing up the collar advances,into the valve casing end, the said tail piece,of a hose for example orthe tubular end of a tap nozzle, 01' so on. the said end being slottedto pass a guard fixed in the valve casing outer end.

The valve has a winged shank adapted to slide in and be guided by partof the valve casing a spindle projecting oppositely to the shank, and awinged spindle-cap adapted to slide in and be guided by another part ofthe casing. The valve has a renewable facing of leather, rubber, orother suitable material, so arranged as not to be likely to rapidlydeteriorate. The aforesaid fixed guard is of special form. In the casingabove the said spindle-cap is a spring connecting the cap and easing.These and other parts will now be described in detail.

In the accompanying drawings, Figures 1 and 9 are views partly in.longitudinal section; Figs. 2 to 8 show details. In Fig. 1 thetail-piece is ready to enter the valve casing; in Fig. 9 it has begun toenter. Fig. 2 shows the valve with its winged shank Specification ofLetters Patent.

and its facing, facing-washer F1gs. 3 and a show in side and end viewrespectively the winged cap which is mounted on the spindle end. Fig. 5shows a guard to be fixed in the valve casing outer end. Fig. 6 showsthe parts in Figs. 4,- and 5 combined looking at the outer face of theguard which hides part of the cap; and Figs. 7, 8 and 9 show positionsof parts during the operation of valve opening, the positions in 7 and 8being retained until the union is disconnected to allow the valve toclose.

a is a valve casing having a screw threaded end Z), for the union nut orcollar, and having means as internal screw thread 0, for connection to afluid supply. Within the casing is a valve seat 2' of any suitabledesign, and beyond it an enlargement (Z formmg a valve chamber. The partj havmg a rubber or suitable facing 76, forms the valve, having a shankcomposed of wings Z (usually four) extending beyond chamber (Z to litthe casing loosely at e. The valve has a spindle m, screw-threaded at aor arran 'ed to carry a washer a to hold down and protect facing la, thespindle tip entering a recess on the inner side of a cap 0 having wings79 which fit the casino; closely at Each wing has a side lug 1" having acurved surface s. A screw g or suitable stud in the valve casing retainsan end of a spring 9 having its other end fixed to can 0 as by enteringa hole in the latter (see Fin. 1) so that when the cap has been slightlyrotated from its normal position, the wind-- ing tension or torsion onthe spring will return the cap to the normal position when the end 10 ofthe tail piece is moved away from the cap. The guard t is shown withradii u to conceal wings 79 when the valve is closed: this guard isfixed as by brazing or otherwise at the casing end, ancL-see Fig. 6-itleaves lugs r uncovered. A screw ]tin the valve casing stud is providedto project and act as a stop between two wings 79. so that cap 0 cannotbe rotated except slightly, thus the spring will return it from theposition illustrated in Fig. 7, to normal as in Fig. 6.

is the collar having a flange 00 to press a flange g on the nozzle 2 sothat end will be advanced into casing a, and open the valve by pressingcap 0 on spindle m. Slots .0 in end w, one to each radius a are providedto allow of the latter being passed.

One side of each slot has a step 10 Fig. 8, and the other side has arounded face 10 l/Vhen end to has advanced past the guard 13 it meetsthe lugs 1" and the pressure of roundlongitudinally and thus movesspindle m, and lifts the valve.

When to release and collar 50 is unscrewed the cap is rotated slightlyand takes its normal position by the action of spring 9. hen the valveis open the flange y presses the casing end I) and prevents leakage, orany other suitable known details for that purpose are used.

Having described this invention, what is claimed by Letters Patent is 1.In a device of the character described, the combination of a valvecasing having a valve seat, a valve in the casing adapted to engage withthe valve seat under fluid pressure, a spindle carried by the valve, awinged cap carried by said valve spindle, a winged guard for said wingedcap secured in said casing, a torsion spring for normally holding saidwinged cap in true register with said winged guard; members carried bysaid winged cap projecting beyond the wings of said guard; a nozzleadapted to enter the valve casing past said wing guard and having meansadapted to engage the winged cap projections to move the wing cap to been gaged by the nozzle; and a member for engaging with the valve casingand holding said nozzle, substantially as described.

2. In a device of the character described, the combination of a valvecasing having a valve seat, a valve in the casing adapted to engage withthe valve seat under fluid pressure, a spindle carried by the valve, awinged cap carried by said valve spindle, a winged guard for said wingedcap secured in said casing, a torsion spring for normally holding saidwingel cap in true register with said winged guard; members carried bysaid winged cap projecting beyond the wings of said guard; a nozzleadapted to enter the valve casing past said winged guard and havingportions adapted to engage the projecting members of the winged cap toposition said cap to be engaged by the nozzle; and a member for engagingwith the valve close the valve the casing and holding said nozzle,substantially as described.

3. In a device of the character described, the combination of a valvecasing having a valve seat, a valve in the casing adapted to engage withthe valve under pressure, a spindle carried by the valve, a winged capcarried by said valve spindle, a winged guard for said winged capsecured in said casing, a torsion spring for normally holding saidwinged cap in true register with said winged guard; members carried bysaid winged cap projecting beyond the wings of said guard; a nozzleadapted to enter the valve casing past said winged guard and havingcurved faces adapted to engage the projecting members of the winged capto move the cap to position for engagement by the nozzle, and shouldersformed on the nozzle adapted to engage with the wings of said cap tounseat the valve; and a member for engaging with the valve casing andholding said nozzle, substantially as described.

t. In a device of the character described, the combination of a valvecasing having avalve seat, a valve in the casing adapted to engage withthe valve seat under fluid pressure, a spindle carried by the valve, awinged cap carried by said valve spindle, a winged guard for said wingedcap secured in said casing, a torsion spring for normally holding saidwinged cap in true register with said winged guard; a stud secured tothe easing and adapted to limit the degree of rotation of the wingedcap; laterally projecting members carried by the wings of said cap andprojecting beyond the wings of said guard; a nozzle having membersadapted to enter the casing through the winged guard and having curvedfaces adapted to engage the projecting members of the winged cap to movethe same to position for engagement by the nozzle, and shoulders formedon the nozzle members adapted to engage with the wings of said cap tounseat the valve; and a member for engaging with the valve casing andholding said nozzle, substantially as described.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
